Rated at 400 V at 50 Hz, it delivers 15 kW in AC-2 duty and 18.5 kW at 500 V, making it suitable for squirrel-cage motors on conveyors, pumps, and fans where the load profile matches AC-2 or AC-3 switching.
The AC-2 rating of 15 kW at 400 V covers slip-ring motor starting where the current stays closer to running levels. Switching frequency limits are 1 000 operations per hour in AC-3 and 750 in AC-2, so it's not meant for high-cycle applications like rapid reversing or jogging — those would need AC-4 rated gear at 250 ops/h. The 10 A at 24 V means it can drive multiple small loads without an interposing relay.
Environmental and Mounting Considerations
IP20 on the front, IP00 at the terminals — the terminal area is open, so it requires enclosure protection against accidental contact. Side-by-side mounting is allowed, which saves rail space in dense panels. Dimensions are 112 mm high, 55 mm wide, 164 mm deep — the S2 frame size fits standard 55 mm-wide contactor slots in most pre-drilled panel layouts.
